AD8622ARMZ

AD8622 is a dual channel precision rail-to-rail output operational amplifier. The device has an input bias current cancellation circuitry that provides a very low input bias current over the full operating temperature. Many systems can take advantage of the low noise, dc precision, and rail-to-rail output swing provided by the device to maximize the signal-to-noise ratio and dynamic range for low power operation. It is widely used in application such as portable precision instrumentation, laser diode control loops, strain gauge amplifiers, medical instrumentation, thermocouple amplifiers etc.
